Yes because when I solve he gets 4 x-intercepts. The x-intercept is a point where the y value is zero.
The degree of a polynomial always determines the number of roots such polynomial function will have;
Given the polynomial function studied by Harvey as g(x) = (4x – 3)(x – 3)(x2 +5)
Taking the product of the leading variables
g(x) = (4x – 3)(x – 3)(x2 +5)
g(x) = 4x(x) (x^2)
g(x) = 4x^4
Since the degree of the polynomial is 4, hence the polynomial has four real roots.

Answer:
It's a rotation of 90 degrees - doesn't matter which way - around the intersection of the two lines
Step-by-step explanation:
Claim: it's a 90 degree rotation around the intersection of f and g.
It's easy to spot the two lines are perpendicular. Let's assume the rotation doesn't happen at the point of intersection [tex]x_0[/tex], but slightly to the side, around let's say, [tex]x_0+\epsilon[/tex]; the new line will coincide with [tex]g(x)[/tex] if and only if [tex]\epsilon = 0[/tex], ie only the rotation happens around the intersection.

8x + 14 y = 4
-6x - 7y=-10
Answer:
y = -2 and x = 4
Step-by-step explanation:
8x + 14y = 4
-6x - 7y = -10
First, find the lowest common multiple of 8 and 6 (which is 24). Multiply the first equation by 3:
8x + 14y = 4
3(8x + 14y) = 3(4)
24x + 42y = 12
Multiply the second equation by 4:
-6x - 7y = -10
4(-6x - 7y) = 4(-10)
-24x - 28y = -40
Now, add the two equations together:
24x + 42y = 12
-24x - 28y = -40
24x + -24x = 0
42y + -28y = 14y
12 + -40 = -28
14y = -28
Divide both sides by 14:
14y ÷ 14 = -28 ÷ 14
y = -2
Plug this known variable back into the first equation:
8x + 14(-2) = 4
8x + (-28) = 4
8x - 28 = 4
Add 28 to both sides:
8x - 28 + 28 = 4 + 28
8x = 32
Divide both sides by 8:
8x ÷ 8 = 32 ÷ 8
x = 4
So y = -2 and x = 4.

Answer:
You look at the sign between y and 2x
Step-by-step explanation:
To find which way to shade, look at your symbol. The symbol you have is a less than or equal to, you shade to the left. Because it has the line underneath, you have a closed circle. (This is for line plots so I don't know if this completely helps)

How many times does 6 go into 719 divison with partial quotient
119.833333333 times it goes into 719 119.833333333 times
Answer:
119 R5
Step-by-step explanation:
we first divide 7 by 6 and we get that it goes in once
so 1__
then after we do 7 - 6 and get a remainder of 1
we drop the 1 next to the other one and get 11
then we divide 11 by 6 and we get that it goes in once
so 11_
then after we do 11 - 6 we get a remainder of 5
we drop the 5 next to the nine and get 59
then we divide 59 by 6 and get 9
so 119
then after we do 59 - 54 and get a remainder of 5
so our answer is 119 R5

In the data set shown, R is an integer. If the median of the data set is 8 and R < 11, what is a possible value
of R?
Answer:
Answers:
R can be either 8, 9 or 10
============================================================
Explanation:
Let's exclude the R value for now.
The set {4,13,5,8,5,11} sorts to {4,5,5,8,11,13}.
Now we'll include R back in. We're told that R is an integer and it's smaller than 11. The possible values R can take on are: {10, 9, 8, 7, ...} The countdown continues forever into the negative territory.
If R < 4, then we go from {4,5,5,8,11,13} to {R,4,5,5,8,11,13}. That R is guaranteed to be the min value since R is less than the smallest value of the previous set. Note that the middle-most item of the second set is 5; however, we want the median to be 8 instead. This allows us to rule out the case that R < 4.
So we've determined that 4 < R < 11. Because R is an integer, we can say it takes on the values from the set {5,6,7,8,9,10}
------------------------------
If R = 5, then {4,5,5,8,11,13} updates to {4,5,5,5,8,11,13} after adding in that R value. We can see the median is 5, so we can rule out the case that R = 5.
Similarly, we can rule out R = 6 as well. The set {4,5,5,8,11,13} updates to {4,5,5,6,8,11,13} in which the median is 6.
If R = 7, then the median is 7 for similar reasoning and we can rule out this R value.
So we've ruled out the cases that R = 5, R = 6 and R = 7.
If we tried R = 8, then {4,5,5,8,11,13} becomes {4,5,5,R,8,11,13} = {4,5,5,8,8,11,13}. This set has a median of 8 and R = 8 is one of the answers.
-------------------------------
Now let's consider the possibility that 8 < R < 11.
If for instance R = 9, then {4,5,5,8,11,13} becomes {4,5,5,8,9,11,13} to show that this set also has a median of 8. R = 9 is another answer.
The same idea happens when R = 10 as well because we get {4,5,5,8,10,11,13}. R = 10 is another answer.
-------------------------------
In short, R can be any of the following values: 8, 9, 10

Simplify the expression √8x^5 / z1
Answer:
3/4
Step-by-step explanation:
Write an equation for each line in slope-intercept form.
Answer:
Line 1 : y = -2x - 5
Line 2 : y = -3x + 3
Step-by-step explanation:
note the slope, and then note the y intercept
Answer:
y = - 2x - 5 and y = - 3x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = - 2, - 1) and (x₂, y₂ ) = (0, - 5) ← 2 points on the line
m = [tex]\frac{-5-(-1)}{0-(-2)}[/tex] = [tex]\frac{x- 5+1}{0+2}[/tex] = [tex]\frac{-4}{2}[/tex] = - 2
The line crosses the y- axis at (0, - 5 ) ⇒ c = - 5
y = - 2x - 5 ← equation of line 1
Repeat with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (1, 0) ← 2 points on line 2
m = [tex]\frac{0-3}{1-0}[/tex] = [tex]\frac{-3}{1}[/tex] = - 3
The line crosses the y- axis at (0, 3 ) ⇒ c = 3
y = - 3x + 3 ← equation of Line 2
